TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN F. W. Domain, of the city and county of Baltimore, and State of Maryland, have invented a new and useful Improvement in Brushesi and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annex ed drawings, making apart of this specification, in \vhich- I V Figure 1 is a perspective view of the brush, as packed and put upbefore being attached to the handle.

Figure 2 is a side view of the brush, showing the cap in section.

Figure 3 is a side view of the instrument when all its parts are put together.

Figure 4 is a longitudinal section of the cap.

In this invention the bristles are put up in separate packages, one of which answers for a brush, and anew but simple and cheap device is employed to attach them to the handle. The packages are designed to be made and sold independently of the handle, to which they can, in a moment, be attached, or from which they can be detached, so that at any time when the bristles wear out or become damaged, they can be removed and new ones substituted. I v

This invention is particularly designed to be applied to the manufacture of stencil-brushes, although paint brushes and other brushes may be put up in the same manner.

A stencil-brush, unlike a paintbrush, cannot be used if thebristles vary'a great deal from a eertainlength, in consequence of which the hair mustbe changed a great deal oftener than that of a paint-brush, and, of course, it is desirable that this change should be effected at as little expense as possible.

When the invention is applied tothe manufacture of paint-brushes, it is equally as convenient and useful, not only allowing the hair to be changed when worn out, but also at anytime for applying different colors. And in putting brushes into water, as all.-- painters do, after using them, they will not be in the slightest degree injured when made in this way. 7

In the drawings, A represents a. package of the bristles, its upper end, a, which is to be attached to the handle, being glued together, so as to form a mass of considerable compactness. Wheuthus formed it is covered with thin paper, as shown at c c c in figs. 1 and 2,'and is sold in this condition,independently of thehandle, and the means for attaching it thereto. 7

The handle is shown at B, and D is a cap or ferrule, by which the package of bristles A is attached to it. The lower end of the ferrule being slightly contracted, as seen at d d, the package A is dropped into it, passing easily through, until the portion a reaches the contracted mouth cl, when it can go no further. The handle is then introduced intothe ferrule or cap, above the bristles, and is screwed down upon them, pressing against the upper end a of the package, and forcing it: downward with great power, firmly fixing it in the socket or cap D. The lower end of the handle is made large enough to fill the bore of the cap or ferrule, and is provided with a screw-thread fitting into a female screw in the latter. i

The bristles having been securely attached to the handle in the manner described, I remove the paper cov ering, c, and the brush then presents the appearance seen in fig.

The whole device is exceedingly simple and cheap, and .will effect a great saving to painters and others who are obliged to use many brushes in the course of their business. In my brush, whenever from any cause the bristles become damaged, they can be removed, and new ones substituted in their place. A single handle and ferrule may thus be made to do duty for years, outlasting many successive packages of bristles. When the bristles work loose, if at any time such should be the case, they can be readily tightened again by a turn of the screw.

A Any suitable composition, glue, or cement, may be employed to fasten the ends of the bristles together at a a.

I have hitherto employed pitch for this purpose, which is found to work well, besides being exceedingly cheap. The use of the paper, it will be observed, is not a material part of the invention, answering no pur pose except that of keeiaing the hairs close together, and preventing them from catching or being forced out of place while inserting them in the handler v Having thus described my invention, xvhat I clniim as new, and desire to secure by Letters Patent, is-- The combination of the pa'elmgeA, when constructed as described, with the handle B, having a male screw on its lower end, and the tapering ferrule D, having at its upper end a female screw, to receive and hold the handle, the several parts being construeted to operate in themanner and for the purposes set forth.
